How to see what apps are using the most memory

Sometimes your device might run slow for no reason. Now you can tell what apps are using the most RAM on your device with a new feature called Memory. Just open Settings and select
Apps and go to Running. You’ll be able to see the average memory used during the last three hours, six hours, 12 hours, or the entire day. You can also tap Memory Used By Apps to find out how much RAM each app has used. This can help you to pinpoint any apps that are using too many resources.
